Nanohaloarchaea as beneficiaries of xylan degradation by haloarchaea

Microbial Biotechnology, Volume 16, Issue 9, Page 1803-1822, September 2023., 2023
Using samples of natural evaporitic brines and anthropogenic solar salterns, we describe genome‐inferred trophic relations in two extremely halophilic xylan‐degrading three‐member consortia. We succeeded in genome assembly and closure for all members of both xylan‐degrading cultures and elucidated the respective food chains within these consortia.

Revisiting the AA14 family of lytic polysaccharide monooxygenases and their catalytic activity

FEBS Letters, Volume 597, Issue 16, Page 2086-2102, August 2023., 2023
The AA14 family of lytic polysaccharide monooxygenases (LPMOs) was discovered in 2018. While these enzymes were originally thought to act on cellulose‐associated xylan, thorough characterization of both a novel and previously studied family members indicates that AA14 LPMOs do not act on cellulose‐associated xylan.

Beyond purified dietary fibre supplements: Compositional variation between cell wall fibre from different plants influences human faecal microbiota activity and growth in vitro

Environmental Microbiology, Volume 25, Issue 8, Page 1484-1504, August 2023., 2023
Abstract Dietary fibre is a major energy source for the human gut microbiota, but it is unclear to what extent the fibre source and complexity affect microbial growth and metabolite production. Cell wall material and pectin were extracted from five different dicotyledon plant sources, apples, beet leaves, beetroots, carrots and kale, and compositional ...

Thermostability of xylanolytic enzymes produced by Lentinula edodes UFV70. [PDF]

Braz J Microbiol, 2012
Xylanolytic enzymes produced by Lentinula edodes UFV70, cultivated in eucalyptus sawdust/rice bran medium, were stable at 50, 60 and 65°C for 21 hours, losing only 15-25% activity. Fungus incubation at 50°C for 12 hours and at 65°C for 24 hours increased the amount of xylose produced.

Discovery of a bifunctional xylanolytic enzyme with arabinoxylan arabinofuranohydrolase‐d3 and endo‐xylanase activities and its application in the hydrolysis of cereal arabinoxylans

Microbial Biotechnology, Volume 16, Issue 7, Page 1536-1547, July 2023., 2023
1. A novel bifunctional xylanolytic enzyme (rAbf43A) was obtained.2. rAbf43A exhibits arabinoxylan arabinofuranohydrolase‐d3 and endo‐xylanase activities.3. rAbf43A shows obvious synergy with cognate bifunctional xylanase/feruloyl esterase. Abstract Xylanolytic enzymes, with both endo‐xylanase and arabinoxylan arabinofuranohydrolase (AXH) activities ...

Fungal‐Based Biorefinery: From Renewable Resources to Organic Acids

ChemBioEng Reviews, Volume 10, Issue 3, Page 272-292, June 2023., 2023
Biorefineries are green facilities in which lignocellulosic biomasses can be transformed into a wide range of bioproducts. For instance, organic acids are interesting molecules, as they find application in several industrial areas. The production of organic acids by filamentous fungi is the preferred route due to their ability to hydrolyze ...

Rational engineering of xylanase hyper-producing system in Trichoderma reesei for efficient biomass degradation

Biotechnology for Biofuels, 2021
Background Filamentous fungus Trichoderma reesei has been widely used as a workhorse for cellulase and xylanase productions. Xylanase has been reported as the crucial accessory enzyme in the degradation of lignocellulose for higher accessibility of ...
